Application filed llanuary 28, 1907. Serial No, 364.511.

To all whom it may concern:

Be it known that I, EDWARD M. WILLIS, a citizen of theUnited States, residing at Kenton, in the county of Hardin and State of Ohio, have invented certain new and useful Improvements in BottlaStoppers, of which the following is a'specification.

My inventionpertains to improvements in bottle stoppers or valves. Its objects are to guard effectively against the accidental escape of the gases of certain liquids from their containing vessel or bottle as when in shi elevation of the same with the eccentric or looking lever in unlocked position. Fig. 3 is a view of the device at right angles to either Fig. 1 or Fig. 2. Fig. 3. i

In the disclosure of my invention, I provide a plug or valve 1 preferably of solid rubber and tapered inward or downward as disclosed, and fitting the correspondin interior surface of the bottle-neck 2. Sai plug or valve has inserted centrally through it a bolt or stem 3 having screwed upon its lower proj cting end a nut 4 between which latter and the plug or valve is inserted a washer 5, said end of bolt or stem bein thus secured in place. Said stem or bolt has its upper endportion projecting some distance beyond said plug or valve; and upon a lateral projection or fulcrum 6 of said bolt or stem, at

' the extreme upper end of the latter, is eccentrically pivoted the cam-ended formation 7. (if a cam-lever 8 which cam-formation is effective to engage a washer 9 arranged upon the stem or bolt 3, next to the upper end of the lug 01' valve 1.

T e lever or handle 8 takes an abrupt' curve at about a relatively right-angle to av horizontal line drawn tangentially to the.

effective edge of the cam-formation 7 whereby, when the cam-lever is in locked or efi'ective position the latter may-occupy a ractically parallel osition and depend c. one to the bottle-nee with its outer extremity outer end in contact with th Fig. 4, is a sectional view of resting against the bottleeneck, as shown by Fig. 1. he extreme outer end of the lever or handle is tapered org? ointed somewhat after the fashion of a bir s talon, as at 1U, particularlyas seen in Fig. 3, adapting especially for use as a cor extractor, as obvious. Also said lever or handle has lat erally projecting therefrom a pointed or hooked stud 10 in order to provide, by suitably applying the lever to a crown -t of cap for bottle-corks, for instance, for tnc engagement of said hook or stud with the lower crimped ed e of said cap and by then pryin upward e ect the displacement or remove of said crown or cap, as will be readily appreciated. It will e noted that, after the insertion of the plug or valve 1 into the bottle neck, the lever or handle at that time ed in the'position indicated I j l g. forcing said lever downwa I necli,' the major axis of the cam-formation T will be brought into forcible engagement with the washer 9, and thus cause the lateral expan sion of said valve or'plug' which will have the efiect to tightly wedge t e latter in said bottie-neck asagainst any possible escape of any gases from the liquid contained in the bottle, as is apparent.

This invention is exceedingly simple in construction, economic in manufacture and readily applied for use, as Well as being highly eiiectlve fpr its intended purpose. 7

I claim 1-. A device as described, comprising a downward-tapering elastic plu a stern extending through said plug, a p ate arranged upon said stem and adjustably held to the lower end of said plug, said stem also extending above and overhanging the upper end of said plug, a lever having a cam-ended formation eccentrically pivoted upon the upper end overhanging portion of said stem, said lever being curved to bring it close, and

cause it practically to conform to the upper portion of the bottleneck.

2. A device as described, comprising a downward tapering elastic plu a stem ex tending through said plug and havin fitted upon its lower end an ad ustably helll plate fitting against the lower end of said'plu a plate applied to the upper end of said p u and having said stem passing through it, sai stem extending beyond and overhanging-the loo ids

flipper end of eaid plug, and a cam-ended In testimohy whereof leflix my SigI1&t1 1I6 kever eccentricallyf pivgted upon the? overin presence of two Witnesses.

en ing portion 0 sai stem and e eotive for 2mga ement with the latter-referred to EDWARD WILLIS 5 plate, sold lever having a curved handled Witnesses:

portion adapted to rest close and conform to HENRY NOHR, the upper end portion of the bottle-neck. A. M. TIDD.
